Description

The present invention relates to a cooking device.

There is a cooking device with multiple front panels fixed to the front of the housing (see, for example, Patent Document 1). The front panels are rectangular, arranged in tiles in the vertical and horizontal directions, and fixed to the mounting target of the cooking device. This forms dividing lines that extend vertically and horizontally on the front of the cooking device.

Some stoves have a high-end aesthetic look, using a front panel with a metal plate attached. In this case, the plate is attached to the front part of a plastic assembly part, for example, so the plastic part may be visible at the front part of the side of the panel. Therefore, it is possible to make the plastic part less visible by forming a bent part in the plate by folding the edge backward, and attaching the plate to the assembly part so that the bent part is positioned at the front part of the side of the panel.

JP 2015-31469 A

However, if the positioning when attaching the plate to the assembly part is set too strictly, for example, due to manufacturing tolerances, interference may occur between the bent part and the side of the assembly part, or a step may occur between the bent part and the side of the assembly part, which may result in a poor appearance. If an operator changes the orientation of the plate to be attached to the assembly part because of interference or a step, the plate may be attached in the wrong orientation.

The object of the present invention is to provide a cooking device that prevents incorrect assembly of the plate and assembly parts and does not spoil the appearance.

The cooking device according to claim 1 of the present invention is a cooking device comprising a cooking device body housing a baking chamber in the center of a housing, and a door for opening and closing the front opening of the baking chamber, and a plurality of plate-shaped plates arranged to cover the front side of the cooking device body, the front side of the cooking device body is provided with a plurality of assembly parts aligned in the vertical and horizontal directions, the plates have a rectangular front plate portion, and are arranged aligned in the vertical and horizontal directions on the front side of the cooking device body by being assembled to the front sides of each of the plurality of assembly parts, the assembly parts being rectangular and comprising a rear plate portion facing the plates, a left-right positioning portion provided at one of the left and right ends of the front side of the rear plate portion and positioning the edge of one of the left and right sides of the plates relative to the edge of one of the left and right sides of the rear plate portion, and and a vertical positioning portion provided at one of the upper and lower ends of the front surface of the rear plate portion for positioning one of the upper and lower edges of the plate relative to the one of the upper and lower edges of the rear plate portion, the plate being made of metal and including: a first plate having the front plate portion, a pair of left and right curved portions which are edges on both left and right sides of the front plate portion and which are respectively bent rearward, and a pair of upper and lower curved portions which are edges on both upper and lower sides of the front plate portion and which are respectively bent rearward; and a second plate having the front plate portion, the pair of left and right curved portions, and an upper curved portion which is an upper edge of the front plate portion and is bent rearward, the assembly portion including the rear plate portion and a pair of upper and lower positioning portions which are portions which extend in the vertical direction and protrude forward at both the left and right ends of the front surface of the rear plate portion, and which have a left-right gap between the left and right edges of the rear plate portion which is larger than the thickness of the plate. a pair of upper and lower protrusions which are portions extending in the left-right direction at both upper and lower ends of the front surface of the rear plate and protruding forward, and which have a vertical gap between the upper and lower edges of the rear plate and a vertical gap larger than the thickness of the plate; the left-right positioning portion which protrudes from one of the pair of left and right protrusions toward the edge of the rear plate on one of the left and right sides and has a gap the same as the thickness of the plate between the edge of the left and right side; and the left-right positioning portion which protrudes from one of the pair of upper and lower protrusions toward the edge of the rear plate on one of the top and bottom sides and has a gap the same as the thickness of the plate between the edge of the top and bottom side; The upper protrusion is a portion that protrudes from the upper edge of the rear plate portion and has a vertical gap between it and the upper edge of the rear plate portion that is larger than the thickness of the plate, the left-right positioning portion protrudes from one of the pair of left-right protrusions toward the left-right edge of the rear plate portion and has a gap between the left-right edge and the left-right edge that is the same size as the thickness of the plate, and a second assembly portion is a portion that protrudes forward at the lower end of the rear plate portion and has the vertical positioning portion that extends in the left-right direction and protrudes forward beyond the pair of left-right protrusions and the upper protrusion, and the assembly in which the plate is assembled to the assembly portion is at least one of a first assembly in which the first plate is assembled to the first assembly portion and a second assembly in which the second plate is assembled to the second assembly portion.

The cooking device according to claim 2 has the same configuration as the cooking device according to claim 1, and is characterized in that the first assembly is arranged in a single left-right direction at least on the upper left side of the door and the upper right side of the door on the front surface of the cooking device body.

The cooking device according to claim 3 has the configuration of claim 1 or 2, and is characterized in that the second assembly is arranged in a single left-right direction at least on the lower left side of the door and the lower right side of the door on the front surface of the cooking device body.

The cooking device according to claim 4 has the same configuration as in claim 1 or 2, and is characterized in that, in the first assembly part, the left-right positioning part is formed on one of the pair of left-right protrusions of the rear plate part, and the up-down positioning part is formed on one of the pair of top-down protrusions of the rear plate part, and the down-down positioning part is formed on one of the pair of top-down protrusions of the rear plate part.

The cooking device according to claim 5 has the same configuration as in claim 1 or 3, and is characterized in that in the second assembly part, the left and right positioning part is formed on one of the pair of left and right protrusions on the rear plate part.

The cooking device according to claim 6 has the configuration of any one of claims 1 to 5, and is characterized in that, in the first assembly part, the left-right positioning part is formed on one of the pair of left-right protrusions of the rear plate part, and the up-down positioning part is formed on one of the pair of top-down protrusions of the rear plate part, and the down-down positioning part is formed on one of the pair of top-down protrusions of the rear plate part.

According to the cooking device of the invention of claim 1 of the present invention, when the plate is assembled to the assembly part, the edge of one of the left and right sides of the plate is abutted against one of the left and right positioning parts of the assembly part, and the edge of one of the top and bottom sides of the plate is abutted against one of the top and bottom positioning parts of the assembly part, so that the plate is positioned at a position where the outer lines of the plates are aligned with respect to the assembly part. Then, the plates with the aligned outer lines are arranged in alignment in the up and down directions and left and right directions on the front surface of the cooking device main body, so that the cooking device has an aesthetic appearance. When the edge of the other of the left and right sides of the plate is mistakenly abutted against the other of the left and right protrusions of the assembly part when the plate is assembled to the assembly part, the edge of one of the left and right sides of the plate protrudes to the side beyond the edge of one of the sides of the assembly part. Or, when the edge of the other of the top and bottom sides of the plate is abutted against the other of the top and bottom protrusions of the assembly part, the edge of one of the top and bottom sides of the plate protrudes to the side beyond the edge of one of the sides of the assembly part. In this case, workers can easily visually check for errors in the assembly of the plate, preventing incorrect assembly of the plate and assembly part and not marring the aesthetic appearance of the cooking appliance.

In addition, when the first plate is assembled to the first assembly part, one of the left and right curved portions of the first plate is brought into contact with the left and right positioning portions of the assembly part, and one of the upper and lower curved portions of the first plate is brought into contact with the upper and lower positioning portions of the assembly part, so that the first plate and the first assembly part are positioned at a position where their respective outer contours are aligned. Since the first plate with its aligned outer contours is placed on the front surface of the cooking device body, the cooking device has an aesthetic appearance. When the first plate is assembled to the first assembly part, if the other of the left and right curved portions of the first plate are mistakenly brought into contact with the other of the left and right protrusions of the first assembly part, the one of the left and right curved portions of the first plate will protrude to the side from the edge of one side of the first assembly part. Alternatively, if the other of the upper and lower curved portions of the first plate are brought into contact with the other of the upper and lower protrusions of the first assembly part, the one of the upper and lower curved portions of the first plate will protrude to the side from the edge of one side of the first assembly part. In this case, the worker can easily visually check for errors in the assembly of the first plate, preventing incorrect assembly of the first plate and the first assembly part and not marring the aesthetic appearance of the cooking appliance.

In addition, the other left and right protrusions and the other upper and lower protrusions of the first assembly part each have a gap between them and the edge of the rear plate part that is larger than the thickness of the plate. This makes it possible to temporarily position the first plate in a position shifted to one side in the left and right direction or one side in the up and down direction, or both, relative to the first assembly part, as long as it is within the range of the size of the gap, making the assembly work easy. If the size of the gap between the other left and right protrusions of the first assembly part and the edge of the rear plate part were the same as the thickness of the first plate, depending on the dimensional variation that may occur during the manufacturing process of the first plate, there is a possibility that the length between the pair of left and right curved parts of the first plate will be shorter than the length between the pair of left and right protrusions of the first assembly part. Alternatively, even if the size of the gap between the other upper and lower protrusions of the first assembly part and the edge of the rear plate part is the same as the thickness of the first plate, the length between the pair of upper and lower curved parts of the first plate may be shorter than the length between the pair of upper and lower protrusions of the first assembly part depending on the dimensional variation that may occur during the manufacturing process of the first plate, and in either case, it may be impossible to temporarily position the first plate relative to the first assembly part. According to this aspect of the present invention, the other left and right curved parts and the other upper and lower curved parts of the first plate do not contact the other left and right protrusions and the other upper and lower protrusions of the first assembly part, respectively, even after the first plate is assembled to the first assembly part. Therefore, the dimensional variation that may occur during the manufacturing process of the first plate can be fully absorbed, and the first plate can be assembled in the correct position relative to the first assembly part.

Similarly, when each of the second plates is assembled to the second assembly part, the lower edge of the second plate is brought into contact with the vertical positioning part of the second assembly part, and one of the left and right curved parts of the second plate is brought into contact with the horizontal positioning part of the second assembly part, so that the second plate and the second assembly part are positioned at a position where their respective outer contours are aligned. The second plate with its aligned outer contours is disposed on the front surface of the cooking device body, so that the cooking device has an aesthetic appearance. When assembling the second plate to the second assembly part, if the other left and right curved part of the second plate is mistakenly brought into contact with the other left and right protrusions of the second assembly part while the lower edge of the second plate is brought into contact with the vertical positioning part of the second assembly part, one of the left and right curved parts of the second plate will protrude to the side beyond the edge of one side of the second assembly part. In this case, the worker can easily visually check the assembly error of the second plate, so that the second plate and the second assembly part can be prevented from being assembled incorrectly, and the aesthetic appearance of the cooking device is not marred.

In addition, the other left and right protrusions of the second assembly part have a gap between them and the edge of the rear plate part that is larger than the thickness of the plate. As a result, when the second plate is assembled to the second assembly part, the second plate can be temporarily positioned at a position shifted to one side in the left-right direction relative to the second assembly part as long as the gap is within the range of the size of the gap, making the assembly work easy. If the size of the gap between the other left and right protrusions of the second assembly part and the edge of the rear plate part is the same as the thickness of the second plate, the length between the pair of left and right curved parts of the second plate may be shorter than the length between the pair of left and right protrusions of the second assembly part, depending on the dimensional variation that may occur during the manufacturing process of the second plate. In this case, it may be impossible to temporarily position the second plate relative to the second assembly part. According to the aspect of the present invention, the other left and right curved parts of the second plate do not contact the other left and right protrusions of the second assembly part even after the second plate is assembled to the second assembly part. Therefore, the dimensional variation that may occur during the manufacturing process of the second plate can be fully absorbed, and the second plate can be assembled in the correct position relative to the second assembly part.

At least one or both of a first assembly having a first plate attached to a first assembly section and a second assembly having a second plate attached to a second assembly section are placed on the front surface of the cooking device body. Whether the first assembly or the second assembly is used alone or in combination, the outer contours are neatly aligned, resulting in an aesthetically pleasing cooking device.

According to the cooking device of the invention of claim 2, in addition to the effects of the invention of claim 1, the first assembly is arranged at least on the upper left side and the upper right side of the door. The first plates with uniform outlines are arranged in the same row (upper row) on the front side of the cooking device body and aligned in the left-right direction, so that the cooking device has an aesthetic appearance.

According to the cooking device of the invention of claim 3, in addition to the effects of the invention of claim 1 or 2, a second assembly is arranged at least on the lower left side of the door and the lower right side of the door. The second plates with uniform outlines are arranged in the same row (lower row) on the front side of the cooking device body and aligned in the left-right direction, so that the cooking device has an aesthetic appearance.

According to the cooking device of the invention of claim 4, in addition to the effects of the invention of claim 1 or 2, when the first plate is assembled to the first assembly part, the first plate is slid from the upper left side to the lower right side relative to the first assembly part, so that the left and right curved parts on the left side of the first plate are positioned by the left and right positioning parts formed on the left and right protrusions protruding from the left end part of the rear plate, and the upper and lower curved parts on the upper side of the first plate are positioned by the upper and lower positioning parts protruding from the upper end part of the rear plate. Since all the first plates are positioned in the same direction, the outlines of all the plates are aligned, creating an aesthetic appearance for the cooking device.

According to the cooking device of the invention of claim 5, in addition to the effects of the invention of claim 1 or 3, when the second plate is assembled to the second assembly part, the second plate is slid from the upper left side to the lower right side relative to the second assembly part, so that the left and right curved parts on the left side of the second plate are positioned by the left and right positioning parts formed on the left and right protrusions protruding from the left end of the rear plate, and the lower end of the second plate is positioned by the up and down positioning part protruding from the lower end of the rear plate. Since all second plates are positioned in the same direction, the outlines of all second plates are aligned, creating an aesthetic appearance for the cooking device.

According to the cooking device of the invention of claim 6, in addition to the effects of the invention of any one of claims 1 to 5, an assembly in which the plate is assembled to the assembly part can be separately produced in advance, and the assembly can be attached to the cooking device in the final stage of cooking device production, thereby suppressing damage to the plate during the production process.

The stove main body 1A includes a housing 2, a grill chamber 10, a left front panel 13, a right front panel 14, decorative panels 61-64, and a decorative panel section 65. The housing 2 has an opening at the top, and a top plate 3 is fixed to the opening. A grill door 8 is provided in the center of the front of the housing 2 so that it can be pulled out toward the front. The grill door 8 opens and closes the front opening of the grill chamber 10 provided inside the housing 2. A grill burner 9 is provided inside the grill chamber 10. A grill window section 15 is provided at the top of the front of the grill door 8. The grill window section 15 is provided with a grill window 17 through which the inside of the grill chamber 10 can be viewed, and a handle 16 that protrudes forward above the grill window 17. On the front of the stove main body 1A, decorative panels 61 and 62 that are approximately rectangular when viewed from the front are attached to the top and bottom of the left side of the grill door 8, and decorative panels 63 and 64 that are approximately rectangular when viewed from the front are attached to the top and bottom of the right side. Additionally, a decorative panel portion 65 that is generally rectangular when viewed from the front is provided at the bottom of the front of the grill door 8. The decorative panels 61 to 64 are removable from the front of the stove body 1A.

When the left decorative panels 61, 62 are removed from the front of the stove body 1A, the front surface of the left front panel 13 is exposed. A battery case (not shown) is provided in the center of the front surface of the left front panel 13.

When the right side decorative panels 63, 64 are removed from the front of the stove main body 1A, the front of the right front panel 14 is exposed. A power switch 19 is provided at the upper front surface of the right front panel 14. An opening 18 is provided at the upper front surface of the decorative panel 63, and the power switch 19 protrudes forward from the opening 18. A grill operation unit (not shown) for operating the grill burner 9 is provided at the lower front surface of the right front panel 14. The grill operation unit is rotatably supported at the lower front surface of the right front panel 14. When the grill operation unit is in use, the decorative panel 64 rotates together with the lower front surface of the right front panel 14, exposing the grill operation unit.

As shown in FIG. 2, in the stove 1, the decorative panels 61-64, the grill window 15, and the decorative panel section 65 are arranged in a tile-like arrangement in two vertical rows and three horizontal rows on the front of the stove main body 1A. The decorative panels 61 and 63 arranged in the upper row have their upper and lower ends aligned at the same height in the vertical direction of the stove 1. The decorative panels 62, 64, and the decorative panel section 65 arranged in the lower row have their upper and lower ends aligned at the same height in the vertical direction of the stove 1. The decorative panels 61 and 62 arranged in the left row have their left and right ends aligned in the horizontal direction of the stove 1. The decorative panels 63 and 64 arranged in the right row also have their left and right ends aligned in the horizontal direction of the stove 1. The grill window section 15 and the decorative panel section 65 arranged in the middle row also have their left and right ends aligned in the horizontal direction of the stove 1. By providing the decorative panels 61-64, the grill window 15, and the decorative panel 65, the stove 1 has vertical and horizontal dividing lines on the front of the stove body 1A, creating an aesthetic appearance as if the front was divided into six parts.

The decorative panels 61-64 and decorative panel portion 65 are formed by attaching a metal plate to the front of a resin mounting portion, resulting in a high-quality, aesthetically pleasing finish. The plate is formed by pressing a metal plate to bend its edges. The mounting portion is formed by injection molding of resin. The mounting portion is provided with a positioning portion that positions the plate when it is mounted to the mounting portion, so that any misalignment due to manufacturing tolerances in the plate and mounting portion is mitigated and the mating portions of the edges of the plate and mounting portion are aligned to achieve an aesthetically pleasing appearance.

The decorative panels 61-64 and the decorative panel portion 65 will be described below with reference to Figures 3 to 7. As shown in Figures 3 and 4, the decorative panels 61, 63 each have a metal plate 71, 73 and a resin plate 81, 83. Note that the decorative panels 61 and 63 have substantially the same configuration, so the following describes the decorative panel 61 and omits the description of the decorative panel 63. The metal plate 71 has a generally rectangular plate shape when viewed from the front, and has a front panel portion 710 that is long in the left-right direction. The upper, lower, left and right edges of the front panel portion 710, that is, the upper curved portion 711, the lower curved portion 712, the left curved portion 713 and the right curved portion 714, are each bent rearward. The length in the front-rear direction of each of the upper curved portion 711, the lower curved portion 712, the left curved portion 713, and the right curved portion 714 is approximately the same as the length by which the protruding portion 817 (described below) of the resin plate 81 protrudes forward from the rear plate portion 810.

The resin plate 81 has a rear plate portion 810 that is generally rectangular in front view and long in the left-right direction. The vertical and left-right lengths of the rear plate portion 810 are generally the same as the vertical and left-right lengths of the metal plate 71. The rear plate portion 810 has a protruding portion 817 on the front surface that protrudes forward in a plate shape. The vertical and left-right lengths of the protruding portion 817 are shorter than the vertical and left-right lengths of the metal plate 71. The upper edge portion 811, the lower edge portion 812, the left edge portion 813, and the right edge portion 814, which are the upper, lower, left, and right edges of the protruding portion 817, are located at the upper end, lower end, left end, and right end of the rear plate portion 810, respectively. The upper edge portion 811, the lower edge portion 812, the left edge portion 813, and the right edge portion 814 have a gap E between them and the upper, lower, left, and right edges of the rear plate portion 810, respectively, that is greater than the thickness D of the metal plate 71.

In addition, an upper positioning portion 815 and a left positioning portion 816 are provided in the gaps E between the upper edge portion 811 and the left edge portion 813 of the protruding portion 817 and the upper and left edges of the rear plate portion 810, respectively. The upper positioning portion 815 is connected to the front surface of the rear plate portion 810 and the upper side surface of the protruding portion 817, and protrudes upward from the upper edge portion 811. Three upper positioning portions 815 are provided side by side in the left-right direction along the upper edge portion of the rear plate portion 810. Each upper positioning portion 815 forms a gap F between the upper edge portion of the rear plate portion 810 and the upper edge portion of the rear plate portion 810, the gap F being the same size as the thickness D of the metal plate 71. Similarly, the left positioning portion 816 is connected to the front surface of the rear plate portion 810 and the left side surface of the protruding portion 817, and protrudes leftward from the left edge portion 813. Three left positioning parts 816 are arranged vertically along the left edge of the rear plate 810. Each left positioning part 816 forms a gap G between itself and the left edge of the rear plate 810, the gap G being the same size as the thickness D of the metal plate 71.

When the metal plate 71 is assembled to the plastic plate 81, double-sided tape is applied to the front surface of the protruding portion 817, and then the metal plate 71 is positioned so as to cover the protruding portion 817 of the plastic plate 81. At this time, there are no positioning portions on the right edge portion 814 and the lower edge portion 812 of the protruding portion 817 of the plastic plate 81. Between the right edge portion 814 and the lower edge portion 812 and the right and lower edges of the rear plate portion 810, there is a gap E that is larger than the thickness D of the metal plate 71. Therefore, the right curved portion 714 can be positioned close to the right side of the right edge portion 814 of the protruding portion 817 as long as it is within the range of the size of the gap E, and the lower curved portion 712 can be positioned close to the lower side of the lower edge portion 812 of the protruding portion 817 as long as it is within the range of the size of the gap E. Therefore, in a front view, the left edge and upper edge of the outline of the metal plate 71 are often positioned slightly protruding to the left and upward from the left edge and upper edge of the outline of the resin plate 81. In this case, the right edge and lower edge of the outline of the metal plate 71 are positioned to the left and upward from the right edge and lower edge of the outline of the resin plate 81. In this way, when placing the metal plate 71 at the assembly start position, there is a sufficient gap between the metal plate 71 and the resin plate 81 to allow for vertical and horizontal shifting. Therefore, the worker performing the assembly can easily place the metal plate 71 at the assembly start position.

When the gap E is the same size as the thickness D (when the gap between the protruding portion 817 and the outer edge of the resin plate 81 is the thickness D of the metal plate 71 around the entire circumference), it is easy to align the outer edges of the metal plate 71 and the resin plate 81 by overlapping the curved portions of the metal plate 71 on the outer sides of the four sides of the protruding portion 817 of the resin plate 81. However, if manufacturing errors cause deviations in the thickness of the metal plate 71 or in the gap between the protruding portion 817 of the resin plate 81 and the outer edge, it may be difficult to assemble the metal plate 71 to the resin plate 81. In this case, in this embodiment, a gap E larger than the thickness D of the metal plate 71 is formed in some parts, so alignment can be easily performed even if there is some manufacturing error.

Next, the metal plate 71 is pressed toward the resin plate 81 while applying a force diagonally downward to the right by the worker. As a result, the metal plate 71 is adhered to the resin plate in a state in which the lower surface of the upper curved portion 711 abuts against the upper positioning portion 815 and the right surface of the left curved portion 713 abuts against the left positioning portion 816. Here, the gap F between the upper positioning portion 815 and the upper edge of the rear plate portion 810 is the same size as the thickness D of the metal plate 71. Also, the gap G between the left positioning portion 816 and the left edge of the rear plate portion 810 is the same size as the thickness D of the metal plate 71. Therefore, in a front view, the left edge and the upper edge of the outline of the metal plate 71 overlap at the same position as the left edge and the upper edge of the outline of the resin plate 81. The upper surface of the upper curved portion 711 is flush with the upper surface of the rear plate portion 810, and the left surface of the left curved portion 713 is flush with the left surface of the rear plate portion 810. The rear plate portion 810 and the metal plate 71 have approximately the same length in the up-down and left-right directions. Therefore, in a front view, the right edge and the bottom edge of the outline of the metal plate 71 overlap at the same position as the right edge and the bottom edge of the outline of the resin plate 81. The bottom surface of the bottom curved portion 712 is flush with the bottom surface of the rear plate portion 810, and the right surface of the right curved portion 714 is flush with the right surface of the rear plate portion 810. In other words, the four edges of the metal plate 71 and the four edges of the resin plate 81 are flush with each other.

If the worker moves the metal plate 71 in the wrong direction and moves it to the left, upward, or diagonally upward to the left relative to the resin plate 81, the lower curved portion 712 or the right curved portion 714, or both, will come into contact with the lower edge portion 812 or the right edge portion 814, or both, of the protruding portion 817. In this case, the decorative panel 61 is finished with the left edge portion or the upper edge portion, or both, of the outline of the metal plate 71 protruding from the left edge portion or the upper edge portion, or both, of the outline of the resin plate 81. Therefore, the worker can easily visually check for errors in the assembly of the metal plate 71.

As described above, the decorative plate 61 is produced by aligning and adhering the metal plate 71 to the resin plate 81 with double-sided tape. Since the outlines of the metal plate 71 and the resin plate 81 are aligned, the decorative plate 61 has a beautiful appearance. The decorative plate 63 is also produced in the same configuration as the decorative plate 61, and therefore has a beautiful appearance.

5 and 6, the decorative panels 62 and 64 each have a metal plate 72 and 74 and a resin plate 82 and 84. The decorative panels 62 and 64 have substantially the same configuration, so the following description will focus on the decorative panel 62 and will omit the description of the decorative panel 64. The metal plate 72 has a substantially rectangular plate shape when viewed from the front and a front panel portion 720 that is long in the left-right direction. The upper curved portion 721, the left curved portion 723, and the right curved portion 724, which are the upper, left, and right edges of the front panel portion 720, are each bent toward the rear. The length in the front-rear direction of each of the upper curved portion 721, the left curved portion 723, and the right curved portion 724 is substantially the same as the length by which the protruding portion 827 (described later) of the resin plate 82 protrudes forward from the rear panel portion 820. The lower edge portion 722 of the front panel portion 720 is not bent.

The resin plate 82 has a rear plate portion 820 that is generally rectangular in front view and long in the left-right direction. The left-right length of the rear plate portion 820 is generally the same as the left-right length of the metal plate 72. The vertical length of the rear plate portion 820 is greater than the vertical length of the metal plate 72. The rear plate portion 820 has a protruding portion 827 on the front surface that protrudes forward in a plate shape. The vertical and horizontal lengths of the protruding portion 827 are shorter than the vertical and horizontal lengths of the metal plate 72. The upper edge portion 821, left edge portion 823, and right edge portion 824, which are the upper, left, and right edges of the protruding portion 827, are located at the upper end, left end, and right end of the rear plate portion 820, respectively. The upper edge portion 821, the left edge portion 823, and the right edge portion 824 have a gap E between them and the upper, left, and right edges of the rear plate portion 820, respectively, that is greater than the thickness D of the metal plate 72.

The lower end of the rear plate portion 820 protrudes forward to form a lower protrusion 822. The lower protrusion 822 extends in the left-right direction along the lower edge of the protrusion 827 and protrudes further forward than the protrusion 827. The vertical length of the metal plate 72 is approximately the same as the vertical length of the rear plate portion 820 excluding the portion where the lower protrusion 822 is formed. In addition, a left positioning portion 826 is provided in the gap E between the left edge portion 823 of the protrusion 827 and the left edge portion of the rear plate portion 820. The left positioning portion 826 is connected to the front surface of the rear plate portion 820 and the left side surface of the protrusion 827, and protrudes leftward from the left edge portion 823. Three left positioning portions 826 are provided in a vertical line along the left edge portion of the rear plate portion 820. Each left positioning portion 826 forms a gap G between itself and the left edge of the rear plate portion 820, the gap G being the same size as the thickness D of the metal plate 72.

When the metal plate 72 is assembled to the resin plate 82, double-sided tape is applied to the front surface of the protruding portion 827, and then the metal plate 72 is positioned so as to cover the protruding portion 827 of the resin plate 82. At this time, there is no positioning portion on the right edge portion 824 of the protruding portion 827 of the resin plate 82. Between the right edge portion 824 and the right edge portion of the rear plate portion 810, there is a gap E larger than the thickness D of the metal plate 72. In addition, since the lower edge portion of the metal plate 72 is not bent, it does not interfere with the rear plate portion 820 of the resin plate 82. Therefore, the right curved portion 724 can be positioned close to the right side of the right edge portion 824 of the protruding portion 827 as long as it is within the range of the size of the gap E. Therefore, in a front view, the left edge portion and the upper edge portion of the outline of the metal plate 72 are often positioned in a state where they slightly protrude to the left and upward, respectively, with respect to the left edge portion and the upper edge portion of the outline of the resin plate 82. At this time, the lower edge of the outline of the metal plate 72 is positioned higher than the upper edge of the outline of the lower protrusion 822 of the resin plate 82. In this way, when placing the metal plate 72 at the assembly start position, there is a sufficient gap between the metal plate 72 and the resin plate 82 to allow for shifting in the vertical and horizontal directions. Therefore, the worker performing the assembly can easily place the metal plate 72 at the assembly start position.

When the gap E is the same size as the thickness D (when the gap between the protruding portion 827 and the outer edge of the resin plate 82 on both the left and right sides and the top side is the thickness D of the metal plate 72), it is easy to align the outer edges of the metal plate 72 and the resin plate 82 by overlapping the curved left and right and top parts of the metal plate 72 on the outside of the three sides of the protruding portion 827 of the resin plate 82. However, if manufacturing errors cause deviations in the thickness of the metal plate 72 or in the gap between the protruding portion 827 of the resin plate 82 and the outer edge, it may be difficult to assemble the metal plate 72 to the resin plate 82. In this case, in this embodiment, a gap E larger than the thickness D of the metal plate 72 is formed in a part, so alignment can be easily performed even if there is some manufacturing error.

Next, the metal plate 72 is pressed toward the resin plate 81 while applying a force diagonally downward to the right by the worker against the resin plate 82. As a result, the metal plate 72 is adhered to the resin plate with the lower surface of the lower edge portion 722 abutting against the upper surface of the lower protrusion portion 822 and the right surface of the left curved portion 723 abutting against the left positioning portion 826. Here, the gap G between the left positioning portion 826 and the left edge of the rear plate portion 820 is the same size as the thickness D of the metal plate 72. Therefore, in a front view, the left edge of the outline of the metal plate 72 overlaps in the same position as the left edge of the outline of the resin plate 81. The left surface of the left curved portion 723 is flush with the left surface of the rear plate portion 820. In addition, since the lower edge 722 abuts against the lower protrusion 822, the lower edge of the outline of the metal plate 72 overlaps with the upper edge of the outline of the lower protrusion 822 of the resin plate 81 in a front view. The lengths of the rear plate 820 and the metal plate 72 in the left-right direction are approximately the same, and the lengths of the rear plate 820 and the metal plate 72 in the up-down direction excluding the portion where the lower protrusion 822 is formed are also approximately the same. Therefore, in a front view, the right edge and the upper edge of the outline of the metal plate 72 overlap with the right edge and the upper edge of the outline of the resin plate 82 in a front view. The right surface of the right curved portion 724 is flush with the right surface of the rear plate 820, and the upper surface of the upper curved portion 721 is flush with the upper surface of the rear plate 820. That is, the left, right, and upper edges of the metal plate 72 and the left, right, and upper edges of the resin plate 82 are neatly aligned without any steps, and the lower edge of the metal plate 72 abuts against the upper end of the lower protrusion 822 of the resin plate 82 without any gaps.

If the worker moves the metal plate 72 in the wrong direction and moves it to the left relative to the resin plate 82, the right bent portion 724 will come into contact with the right edge portion 824 of the protruding portion 827. In this case, the decorative panel 62 is finished with the left edge portion of the outline of the metal plate 72 protruding from the left edge portion of the outline of the resin plate 82. Therefore, the worker can easily visually check for errors in the assembly of the metal plate 72.

As described above, the decorative plate 62 is produced by aligning and adhering the metal plate 72 to the resin plate 82 with double-sided tape. Since the outlines of the metal plate 72 and the resin plate 82 are aligned, the decorative plate 62 has an aesthetic appearance. The decorative plate 64 is also produced in the same configuration as the decorative plate 62, and therefore has an aesthetic appearance.

As shown in FIG. 7, the decorative panel portion 65 is provided at the lower stage of the grill door 8. The decorative panel portion 65 has a metal plate 75 and a resin plate portion 85. The metal plate 75 is different in size from the metal plate 72 but has a substantially similar configuration, and has a front plate portion 750 and an upper curved portion 751, a left curved portion 753 and a right curved portion 754 that are bent backward at the upper, left and right edges. The lower edge portion 752, which is the lower edge, is not bent.

The resin plate portion 85 is a part that constitutes the lower stage of the grill door 8, and is connected to the upper stage grill window portion 15 and cannot be removed. The resin plate portion 85 is different in size from the resin plate 82, but the assembly structure of the metal plate 75 is similar, and has a rear plate portion 850, a protruding portion 857, a lower protruding portion 852, and a left positioning portion 856. The gap E between the upper edge portion 851, the left edge portion 853, and the right edge portion 854, which are the upper, left, and right edges of the protruding portion 857, and the upper, left, and right edges of the rear plate portion 850, is larger than the thickness D of the metal plate 75. The gap G between the left positioning portion 856 and the left edge of the rear plate portion 850 is the same size as the thickness D of the metal plate 75.

When the metal plate 75 is assembled to the resin plate portion 85, the metal plate 75 is arranged to cover the protruding portion 857 of the resin plate portion 85, similar to the decorative plate 62. Since there is a sufficient gap between the metal plate 75 and the resin plate portion 85 to allow the metal plate 75 to be shifted in the vertical and horizontal directions, the metal plate 75 can be easily arranged at the assembly start position. The metal plate 75 is pressed toward the resin plate portion 85 while a force is applied to the resin plate portion 85 obliquely downward to the right, so that the lower surface of the lower edge portion 752 abuts against the upper surface of the lower protruding portion 852, and the right surface of the left curved portion 753 abuts against the left positioning portion 856. As a result, the left curved portion 753 and the lower edge portion 752 of the metal plate 75 are positioned on the resin plate portion 85, and the outer contours of the metal plate 75 and the resin plate portion 85 are aligned, so that the decorative plate portion 65 has a beautiful appearance.

In this way, when the metal plates 71-75 of the decorative panels 61-64 and decorative panel portion 65 of the stove 1 are assembled to the plastic plates 81-84 and plastic plate portion 85, they are all slid from the upper left to the lower right. This reduces the possibility of assembling in the wrong orientation, and the outlines of the metal plates 71-75 and the plastic plates 81-84 and plastic plate portion 85 are perfectly aligned, especially at the left edge, giving the stove 1 an aesthetic look.

As explained above, when the metal plates 71-75 are assembled to the plastic plates 81-84 and plastic plate portion 85, the left curved portions 713, 723, 753 of the metal plates 71-75 are brought into contact with the left positioning portions 816, 826, 856 of the plastic plates 81-84 and plastic plate portion 85, and the upper curved portions 711 and lower edge portions 722, 752 of the metal plates 71-75 are brought into contact with the upper positioning portion 815 and lower protrusions 822, 852 of the plastic plates 81-84 and plastic plate portion 85, so that the metal plates 71-75 are positioned in a position where their respective outlines align with the plastic plates 81-84 and plastic plate portion 85. The metal plates 71-75, whose outlines are aligned, are then aligned vertically and horizontally on the front surface of the stove body 1A, resulting in a beautiful appearance for the stove 1. When assembling the metal plates 71-75 to the resin plates 81-84 and the resin plate portion 85, if the right curved portions 714, 724, 754 of the metal plates 71-75 are mistakenly brought into contact with the right edge portions 814, 824, 854 of the resin plates 81-84 and the resin plate portion 85, the left curved portions 713, 723, 753 of the metal plates 71-75 will protrude laterally beyond the left edge portions of the resin plates 81-84 and the resin plate portion 85. Alternatively, if the lower curved portions 712 of the metal plates 71-75 are brought into contact with the lower edge portion 812 of the resin plates 81-84 and the resin plate portion 85, the upper curved portions 711 of the metal plates 71-75 will protrude laterally beyond the upper edge portions of the resin plates 81-84 and the resin plate portion 85. In this case, workers can easily visually check for errors in the assembly of the metal plates 71-75, which prevents incorrect assembly of the metal plates 71-75 and the plastic plates 81-84 and plastic plate portion 85, and does not spoil the aesthetic appearance of the stove 1.

In addition, the right edge portions 814, 824, 854 and the lower edge portion 812 of the protruding portions 817, 827, 857 of the resin plates 81-84 and the resin plate portion 85 have a gap E between them and the edges of the rear plate portions 810, 820, 850, respectively, which is larger than the thickness D of the metal plates 71-75. As a result, when the metal plates 71-75 are assembled to the resin plates 81-84 and the resin plate portion 85, as long as it is within the range of the size of the gap E, the metal plates 71-75 can be provisionally positioned in a position offset to one side in the left-right direction or one side in the up-down direction, or both, relative to the resin plates 81-84 and the resin plate portion 85, making the assembly work easier. If the size of the gap E between the right edge portions 814, 824, 854 of the protruding portions 817, 827, 857 of the resin plates 81-84 and the resin plate portion 85 and the edge portions of the rear plate portions 810, 820, 850 were the same as the thickness D of the metal plates 71-75, depending on the dimensional variations that may occur during the manufacturing process of the metal plates 71-75, there is a possibility that the length between the left curved portions 713, 723, 753 and the right curved portions 714, 724, 754 of the metal plates 71-75 will be shorter than the length between the left and right edge portions (including the left positioning portions 816, 826, 856) of the protruding portions 817, 827, 857 of the resin plates 81-84 and the resin plate portion 85. Alternatively, if the size of the gap E between the upper edge portion 811 of the protrusion 817 of the resin plates 81, 83 and the edge of the rear plate portion 810 is the same as the thickness D of the metal plates 71, 73, depending on the dimensional variations that may occur during the manufacturing process of the metal plates 71, 73, the length between the upper curved portion 711 and the lower curved portion 712 of the metal plates 71, 73 may be shorter than the length between the upper and lower edge portions (including the upper positioning portion 815) of the protrusion 817 of the resin plates 81, 83, and in either case, it may not be possible to temporarily position the metal plates 71-75 relative to the resin plates 81-84 and the resin plate portion 85. In this embodiment, the right curved portions 714, 724, 754 and the lower curved portion 712 of the metal plates 71-75 do not come into contact with the right edge portions 814, 824, 854 and the lower edge portion 812 of the protruding portions 817, 827, 857 of the resin plates 81-84 and the resin plate portion 85, respectively, even after the metal plates 71-75 are assembled to the resin plates 81-84 and the resin plate portion 85. Therefore, the dimensional variations that may occur during the manufacturing process of the metal plates 71-75 can be fully absorbed, and the metal plates 71-75 can be assembled in the correct position relative to the resin plates 81-84 and the resin plate portion 85.

The decorative panels 61-64 and the decorative panel portion 65 are arranged on the front of the stove body 1A, which is divided into six sections: the upper and lower sections on the front side of the left front panel 13, the upper section (grill window section 15) and lower section of the grill door 8, and the upper and lower sections on the front side of the right front panel 14, excluding the grill window section 15. The decorative panels 61-64 and the decorative panel portion 65 are arranged in alignment in the vertical and horizontal directions, giving the stove 1 an aesthetic appearance.

When the metal plates 71-75 are assembled to the resin plates 81-84 and the resin plate portion 85, the metal plates 71-75 are slid from the upper left side to the lower right side relative to the resin plates 81-84 and the resin plate portion 85, so that the left curved portions 713, 723, 753 of the metal plates 71-75 are positioned by the left positioning portions 816, 826, 856 formed on the left edge portions 813, 823, 853 of the protruding portions 817, 827, 857 of the rear plate portions 810, 820, 850. In addition, the upper curved portions 711 or lower edge portions 722, 752 of the metal plates 71-75 are positioned by the upper edge portion 811 of the protruding portion 817 of the rear plate portion 810, or the lower protruding portions 822, 852 of the rear plate portions 820, 850. All metal plates 71-75 are positioned in the same direction, so the outlines of all metal plates 71-75 are aligned, creating an aesthetic look for the stove 1.

As described above, decorative panels 61, 63 and decorative panels 62, 64 and decorative panel portion 65 have different metal plate assembly configurations, but even when both are used together, the outlines are neatly aligned, resulting in a beautiful appearance for stove 1. By using decorative panels 61, 63 on the upper level and decorative panels 62, 64 and decorative panel portion 65 on the lower level, decorative panels 61-64 and decorative panel portion 65, which have aligned outlines, are aligned in the left-right direction on the same level (lower level) on the front of stove main body 1A, resulting in a beautiful appearance for stove 1.

The decorative panels 61-64 are made in advance by assembling the metal plates 71-74 with the resin plates 81-84, and the decorative panels 61-64 can be attached to the stove 1 in the final stage of the production of the stove 1, which prevents the metal plates 71-74 from being damaged during the production process.

The present invention is not limited to the above embodiment, and various modifications are possible. The front surface of the stove body 1A is divided into six sections by the decorative panels 61, 63, the decorative panels 62, 64, the decorative panel portion 65, and the grill window portion 15, but the number of divisions may be more than six or less than six. For example, the decorative panels 61, 62 and the decorative panels 63, 64 may each be integral. Alternatively, the decorative panels 61, 62 and the decorative panels 63, 64 may each be divided into three in the vertical direction. Or, the decorative panels 61, 62 and the decorative panels 63, 64 may each be divided into two in the horizontal direction.

The decorative panels 61 and 63 and the decorative panels 62 and 64 and the decorative panel section 65 have different configurations of the positioning parts in the up and down direction, but they may all have the same configuration. For example, the decorative panels 62 and 64 and the decorative panel section 65 may be configured with an upper positioning part 815 and no lower protrusions 822 and 852. In other words, like the decorative panels 61 and 63, a type of decorative panel and decorative panel section that does not have a lower protrusion and positions the metal plate by one of the left and right positioning parts and one of the top and bottom positioning parts may be used for all the decorative panels 61 to 64 and the decorative panel section 65 provided on the stove 1. Alternatively, the decorative panels 61 and 63 may be configured without the upper positioning part 815 and with the lower protrusions 822 and 852. In other words, decorative panels and decorative panel sections of the type that have a downward protrusion and that position the metal plate together with a positioning section on either the left or right side, such as decorative panels 62, 64 and decorative panel section 65, may be used for all decorative panels 61 to 64 and decorative panel section 65 provided on stove 1.

The decorative panel 65 is configured so as not to be removable from the grill door 8, but it may be removable. Also, the decorative panels 61-64 are configured so as to be removable from the front of the stove body 1A, but they may be configured so as not to be removable. The left positioning parts 816, 826, 856 may be provided on the right side, and the upper positioning part 815 may be provided on the lower side. Also, protrusions similar to the lower protrusions 822, 852 may be provided on the upper, left, and right ends of the rear panels 810, 820, 850.

As shown in Figures 8 and 9, the number of left positioning parts 886, 896 and the number of upper positioning parts 885, 895 do not have to be three, but may be one or more. As with the left positioning part 896 and the upper positioning part 895, if there is only one, it is preferable that the shape extends in the same direction as the corresponding edge part.

The upper edge portions 811, 821, 851, the lower edge portion 812, the left edge portion 813, 823, 853, and the right edge portion 814, 824, 854 are the four edges of the protrusions 817, 827, 857, but as shown in FIG. 8, they may be independent protrusions 881, 882, 883, 884, respectively. Alternatively, as shown in FIG. 9, there may be no protrusions, and the left positioning portion 896 and the upper positioning portion 895 may be provided separately. In this case, it is advisable to provide a separate protrusion 897 for attaching a metal plate.

The metal plates 71-75 are not limited to being made of metal, but may be made of a material whose surface is treated to provide a beautiful appearance or texture. Of course, they may be made of resin. The resin plates 81-84 and the resin plate portion 85 are not limited to being made of resin, but may be made of metal, for example.

When preparing the decorative plate 61, the metal plate 71 is placed so as to cover the protruding portion 817 of the resin plate 81, and after being slid diagonally downward to the right while slightly raised from the resin plate 81, it is attached with double-sided tape. This method is not limited to the above, and the metal plate 71 may be assembled by fitting it into the resin plate 81. For example, after applying double-sided tape to the resin plate 81, the rear end of the left curved portion 713 of the metal plate 71 is abutted against the gap G between the left positioning portion 816 of the resin plate 81 and the left edge of the rear plate portion 810. Using the abutting portion as a fulcrum, the right curved portion 714 side is pushed backward, and the metal plate 71 is placed on the front side of the resin plate 81 so as to cover the protruding portion 817. When the four curved portions of the metal plate 71 are positioned outside the four edges of the protruding portion 817 and the protruding portion 817 is covered with the metal plate 71, the metal plate 71 is pressed diagonally downward to the right against the resin plate 81, and the metal plate 71 is fitted into the protruding portion 817. As a result, the upper curved portion 711 and the left curved portion 713 come into contact with the upper positioning portion 815 and the left positioning portion 816, respectively, and the metal plate 71 is fitted into the protruding portion 817 in a positioned state, and is adhered to the resin plate 81 by the double-sided tape. In this way, when fitting the metal plate 71, the metal plate 71 is rotated around the left curved portion 713 that comes into contact with the left positioning portion 816 as a fulcrum, and is aligned and attached, whereby the metal plate 71 can be easily and accurately assembled to the resin plate 81 by a simple procedure. The decorative plates 62 to 64 and the decorative plate portion 65 may also be manufactured by a similar procedure. Alternatively, the metal plate 71 may be rotated around the upper curved portion 711 of the metal plate 71 as a fulcrum to align and attach it to the resin plate 81.
